stricted to the ,character of type-action emframe` which constitutes (a beaingf'for the ...other end `fofthe carrier or shaft'. A collar. inside jthframe 1. of .the machine and isjsecured n'P'SitiOIi-On .thefshaft by a set-screw-16?,'thus'preventing a displac'ementfof the shaft from `its bearings. The shaft extends transverselyffof the lseries kof kei-levers. 3 and at one. `end thereof pro-- t llis `seatedonthe shaft jects eyQnd the` side off theframey ofthe Ina,-

Y yderstood that the invention'is in sense rev v ne -side of the frame of' thel machine is. tapped for thereceptibn of a screw 14, which'. isprovided with a'bearing 15 `atfthe -in'ner end thereof, said .bearingbeing adapted.V to support one `end of afho'llow or tubular shaft-or l carrier. 16, they opposite end of'whichis seatedr A1n an aperture ingtl'ieA` opposite vside of the i chine, as illustratedfin.Fig.Y 2, and is llattened at twofside's tl1ereof,fas indicated r:it-'17in Fig. 6. ;A ratchet-wheel .1"8 has a bore that rameof thefrnachineand 1sadapted`to be seated thereon, so that the ratchet-wheel and shaftareconnected to turn toget'her.` The shaft extends beyondgthat'portwnon which the ratchet-wheel isseated and" is exteriorly threadedV at 19 for the-reception -ofy a 1inger-'iece or knurled head 20, by means of the shaft can beturne'd `toaford the desired adjustment; but, if desired, the shaft may be turned by means of a pin :fitted into a capstan-hole 2,0a either in the- 'shaft or in the knob. Pivot'edl to the framing 1' of the Inachine at 2l is a pawl 22,. which. has a leafspring 23 secured theretojat 24, .the'freeend of saidspring bearing'against aiXed pin 25 and. tending to maintain the nose ofthe pawl 1n en agementwith-the teeth of the ratchetso. that the' ratchet-Wheel and shaft may bemaintainedfin the position to'which turned. Theshaft 1.6 has a longitudinal slot 26 therein, and Eone Wall of sai j,slot lis provided with a series kif-notches, a@ 'fr'turea er depressions 27, that vare spaced at equal disart vand eor'respfmd,V substantially to the s aclng of the key-levers; The widt of the's ot is referably less than the reatest diameter o the bore of the hollow s aft, so

that the slot forms a contracted mouth which one end 28 of each 2f the key- *i 7.5 corresponds-.to .thecontour of'th'e shaft or `carrierwhereit extends be ond the-sid'eiory lever-restoring sprin may. extendz .as rep--- resented in Fig. 1, an so that the coll' or loop 29 of each spring may be seated within the hollow shaft and confined against withdrawal through the longitudinal slot. Each restoring-spring has one end thereof formedv as a finger 30, winch is adapted to project into one of the recesses 27 in the shaft in order to reception of a key-lever.

From the foregoing description it will be understood that by turning the knurled head or finger-piece 2O a simultaneous adjustment" of the tension of all of the restoring-sprin s mayl be eected and thatjthe tension of al the springs will be adjusted to a like degree. If, for instance, it is desired to place more n tension on the springs, the shaft or carrier 1s turned in the direction ofthe arrow in Fig. 1 tothe desired extent,an d the pawl 22 will c0- o` erate with the'ratchet-Wheel to maintain t e carrier or hollow shaft in the position to which it has been adjusted. If, on the other hand, the tension on the springs is to be decreased, the pawl 22 may be disenga ed from the teeth of the ratchet-wheel 18, w 'le the knurled head 20 is grasped and a turning i' i' of the shaft to the desired extent in a direction-'opposite to that indicated by the arrow in Fig. 1 may bel ermitted. The pawl is thenreleased, and t e'shaft or carrier will he Y the position to which it is adjusted V Y x From the foregoing descriptlon it will be seen that VI have provided a simple, cheap, and efficient devicefor mounting the various restoring-springs for the key-levers and for simultaneously effecting an adjustment of all of them to a like degred that the provision of means on the outside of the framing of the machineaifords access to the hollow shaft or carrier for the 'springs in order that the adjustment of the tension thereof may be readily effected.

Various changes in details of construction may be made without departing from the spirit of my invention.-

What I claim as new', and desire to secure by Letters'Patent, is-

1. In a type-writing machine, the combination of type-actions, a hollow or tubular rock-shaft, means for turning said rock-shaft, and a plurality of springs seated-in said hollo'w shaft and each connected `to said shaft and to an element of a type-action.

2. In a type-writing machine, the combination of type-actions, a hollow or tubular adustable carrier, and a series of sprin s, each a'ving a coil or loop contained in sai hollow carrier and each'eonnected to said carrier and to en element of a type-action.

3. In a type-writing machine, the combination of type-actions, a hollow shaft,means for turning said shaft and a, series of springs, each havin a coil or loop contained 1n said hollow sha t and each-'having yone end connected thereto and the other end connected to an element of a type-action.

In-a type-writing machine, the combination of type-actions, a hollow shaft that has a longitudinal slot therein, means f r adjustinlgl'said shaft, and a series of springs .each of w ch has a coil or loop that is seated in vsaid hollow shaft and with one end of each s ring connected to the shaft and the other en projecting through the longitudinal slot' therein and'connecting with an element of a type-action.

5. In a type-Writing machine, the combi- -nation of type-actions, an adjustable carrier that has an open longitudinal slot therein with regularly-s aced notches or recesses in one wall of sai slot, and a series of sprin s each of which has one end seated in a noto or recess in the carrier and the other end projecting through the longitudinal slot and connecting with an element of a type-actlon.

6. In a type-writing'machine,the combination of type-actions, a hollow shaft that has an open longitudinal slot therein with regularly-s aced notches or recesses in one wall thereo ,means for tu'rningsaid shaft and for retaining it in= the position to` which it is turned, and a seriesofsprings, ea h of which has a coil or loop that is containsg within-the shaft, one end of each spring be' g seated 1n a notchin thel `shaft an the other end prejecting through'the longitudinal slot therein and connecting with an element ofta type-action.
